I had been reading some classified information for years and the majority of those Top Secret documents, I think, are really stupidities, like gossip news published in women's magazines. The
only one information I know that could cause serious commotion among
population of North Hemisphere's countries; with possible mass flight
from their countries, loss of many lives, murder and mass disturbances
is:90% of World Population in North Hemisphere would die by 2050 due to climate change (no water, no food)Perhaps
by 2030, some rich countries like U.S., Canada, U.K., France, Germany
and Russia plan to send some of their young people (less than 30 years
old, well educated, white skin and high I.Q. levels) to live in South
American countries (Argentina, Brazil, Chile, Uruguay and others).http://onlinedatingsoundbarrier.blogspot.com.ar/2013/11/espionage-is-for-economic-interests.html

the "Fat Man"
The RDS-1 explosion yielded 22 kilotons of TNT, similar to the American Gadget and Fat Man bombs.

The B-29
The Tupolev Tu-4 was
a piston-engined Soviet strategic bomber that served the Soviet Air
Force from the late 1940s to mid 1960s. It was a reverse-engineered copy
of the U.S.-made Boeing B-29 Superfortress.

The Concorde
The Tupolev Tu-144
was the world's first supersonic transport aircraft (SST). The design,
publicly unveiled in January 1962, was constructed under the direction
of the Soviet Tupolev design bureau, headed by Alexei Tupolev.

The Shuttle
The Buran spacecraft was a Soviet orbital vehicle analogous in function and design to the US Space Shuttle.

The Intel 8086
The 8086
(also called iAPX 86) is a 16-bit microprocessor chip designed by Intel
between early 1976 and mid-1978. The electronics industry of the Soviet
Union was able to replicate the 8086 through both industrial espionage
and reverse engineering. The resulting chip, K1810BM86, was binary and
pin-compatible with the 8086, but was not mechanically compatible
because it used metric measurements.
